Using the Auxiliary Input Jack
AUX IN (Auxiliary Input): The radio system has
an auxiliary input jack located on the lower
right side of the faceplate. This is not an audio
output. Do not plug the headphone set into
the front auxiliary input jack. An external audio
device such as an iPod, laptop computer,
MP3 player, CD changer, or XM™ receiver, etc.
can be connected to the auxiliary input jack for use
as another source for audio listening.
The auxiliary input jack also accepts cell phone
connectors. Plug the cell phone connector into the
auxiliary input jack to hear a person speck on a
cell phone during a conversation through the
vehicle sound system.
Drivers are encouraged to set up any auxiliary
device while the vehicle is in PARK (P). See
Defensive Driving on page 206 for more
information on driver distraction.
To use a portable audio player, connect a 3.5 mm
(1/8 inch) cable to the radio's front auxiliary
input jack. While a device is connected, turn the
portable audio player on and press the radio
CD/AUX button to hear audio from the device over
the vehicle speakers.
(Power/Volume): Turn this knob clockwise or
O
counterclockwise to increase or decrease the
volume of the portable player. Additional
adjustments on a portable device might be needed
to get the desired volume.
CD/AUX (CD/Auxiliary): Press this button once
to play a CD while a portable audio device is
playing. Press this button a second time for the
system to begin playing audio from the connected
portable audio player. Once in this mode,
"Auxinput" appears on the display. If the auxiliary
jack does not detect the presence of an output
jack, the auxiliary mode does not display.
